dc.description.abstractStudies on the effects of sowing densities on maize grain yields under irrigation were performed with the aim of creating favourable conditions for plant growth and development, under which the genetic yield potential would be maximally exploited. A two-factorial trial was performed in the period 2006-2009 on chernozem, according to the split- plot method with four replicates. Four maize hybrids of different FAO maturity groups (ZP 341, ZP 434, ZP 684 and ZP 704) were observed in combination with seven sowing densities (G1 - 40,816 plants ha-1, G2 - 50,125 plants ha-1, G3 - 59,524 plants ha-1, G4 - 69,686 plants ha-1, G5 - 79,365 plants ha-1, G6 - 86,286 plants ha-1 and G7 - 98,522 plants ha- 1). The obtained results showed statistically very significant differences in maize grain yields between the studied hybrids and the sowing densities. The lowest yields were recorded for all studied hybrids at the lowest sowing density (40,816 plants ha-1). The regression analysis indicated that, depending on a maize hybrid, the following maximum yields could be expected: ZP 341 - 13.25 t ha-1 at a sowing density of 81,000 plants ha-1, ZP 434 - 13.00 t ha-1 at a sowing density of 75,000 plants ha-1 , ZP 684 - 13.83 t ha-1 at a sowing density of 82,000 plants ha-1 and ZP 704 - 12,83 t ha-1 at the sowing density of 77,000 plants ha-1. In accordance with the rational use of seeds, high yields are obtained by sowing that provides 50,000 plants of ZP 434 ha-1, 60,000 plants of ZP 341 ha-1 and ZP 704 ha-1 and 70,000 plants of ZP 684 ha-1.en
dc.description.abstractU cilju stvaranja povoljnih uslova za rast i razviće biljaka, pri kojima se maksimalno koristi genetički potencijal rodnosti, obavljena su proučavanja uticaja gustine setve na visinu prinosa zrna kukuruza gajenog u navodnjavanju. Dvofaktorijalni ogled izveden je u periodu 2006-2009 na černozemu, po metodi razdeljenih parcela u četiri ponavljanja. Ispitivano je četiri hibrida kukuruza različite FAO grupe zrenja (ZP 341, ZP 434, ZP 684 i ZP 704) u kombinaciji setve sa sedam gustina (G1 - 40000 bilj.ha-1, G2 - 50000 bilj.ha-1, G3 - 60000 bilj.ha-1, G4 - 70000 bilj.ha-1, G5 - 80000 bilj.ha-1, G6 - 90000 bilj.ha-1, G7 - 100000 bilj.ha-1). Dobijeni rezultati pokazuju da su između ispitivanih hibrida i gustina setve ostvarene statistički veoma značajne razlike prinosa zrna kukuruza. Svi ispitivani hibridi najniže prinose su ostvarili pri najmanjoj gustini setve, sa 40.000 bilj.ha-1. Regresiona analiza pokazuje da se zavisno od hibrida kukuruza mogu očekivati sledeći maksimalani prinosi zrna: ZP 341 - 13,25 tha-1 pri gustini setve 81.000 bilj.ha-1, ZP 434 - 13,00 tha-1 pri gustini 75.000 bilj.ha-1 , ZP 684 - 13,83 tha-1 pri gustini 82.000 bilj.ha-1 i ZP 704 - 12,83 tha-1 pri 77.000 bilj.ha-1. U skladu sa racionalnom upotrebom semena, visoki prinosi se dobijaju setvom koja obezbeđuje po hektaru 50.000 biljaka hibrida ZP 434, zatim 60.000 biljaka hibrida ZP 341 i ZP 704 i 70.000 biljaka ZP 684.sr
